Here it is explicitly:

class MyClass

  def num=(val)
    @num = val
  end

  def num
      @num
  end

  def initialize(val)
    @num = val
  end

end

t = MyClass.new(1)
puts t.num


which is equivalent to:

class MyClass
  attr_accessor :num

  def initialize(val)
    @num = val
  end

end

t = MyClass.new(1)
puts t.num
